CO OZNACZA SŁOWO ASTROCOMPASS
Astrocompass
Astrocompass jest narzędziem nawigacyjnym do określania kierunku prawdziwej północy poprzez pozycje różnych organów astronomicznych. Są pewne okoliczności, kiedy magnetyczne kompasy i żyroskrzydły są niewiarygodne. Najbardziej oczywistym jest w rejonach polarnych, gdzie siła wywierana na igłę magnetycznego kompasu jest prawie pionowa, a gwiazdy zginają w wyniku obrócenia Ziemi. Magnetyczne kompasy są również podatne na zakłócenia spowodowane przez pola magnetyczne inne niż Ziemia, takie jak te wytwarzane przez kadłuby niektórych metalowych pojazdów lub jednostek. Przed pojawieniem się elektronicznych narzędzi nawigacyjnych, takich jak GPS, najbardziej wiarygodnym sposobem na ustalenie północy w takich okolicznościach było wykorzystanie astro-mostu.

The Astrocompass At high latitudes, where magnetic variation can be erratic and
the angle of magnetic dip can be steep, the magnetic compass is essentially
useless. As the need for flights at high latitudes and/or near the magnetic pole, ...

As far as the intercept is concerned, it will be accurate and plottable as long as
the coordinates set into the Astrocompass are within 60 to 70nm of the current fix.
Beyond this distance lock-on can be maintained, but plotting becomes a problem.

Dutton's Nautical Navigation
One practical method is to mount an astrocompass on or parallel to the ship's
centerline (see fig. 3407). While a Sun compass can be useful, it needs a shadow
from the Sun to give useful data. The astrocompass can be used with the Sun or ...

The astrocompass is an instrument designed primarily for the determination of
the true heading of an aircraft. When the exact true heading is known, the local
magnetic variation can be applied to obtain the magnetic heading. This value can
